I have only just started CADing a few weeks ago and at first my weight went up 4lbs but now that the metabolic effect is starting to happen I am beginning to lose and have now lost 4.8 lbs in the last week. Sometimes we just have to let the body do it's thing. If your caloric intake is too low your body could still be in 'diet.. panic 'mode and hanging on because it's been there before. The brain remembers and reacts accordingly. being your second time it may take longer before it begins to work.
It's frustrating isn't it?? hang in there
